"A guide to performing an SEO audit" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Enables agents and audit systems to hash execution logs into tamper-proof Merkle trees, compute cryptographic inclusion proofs, and verify audit-trail integrity on demand. It runs as a zero-dependency Python MCP server (stdio JSON-RPC) or as an importable module, exposing anchoring, proof generation, and integrity verification over local agent activity records.

Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Performs static security analysis of Solana programs and generates x402 payment invoices for automated agent-to-agent audit workflows.

An MCP server that provides authorization middleware for AI agents using private data, enabling consent management on Aleo and local private inference with persistent policy storage.

An AI-driven platform for analyzing Polymarket prediction markets using on-chain data, offering smart money tracking, sentiment analysis, and arbitrage detection via natural language queries.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

An MCP server that provides programmable spend limits and audit trails for AI agents to make payments from a dedicated wallet, preventing overspend and unauthorized transactions.

Enables AI agents to enforce configurable spending policies before executing trades or x402 payments via Binance Agent OS, recording every policy decision onchain to an Ethereum Sepolia audit log.

An MCP server that enables AI agents to manage merchant payment processing through the BTCPay Server Greenfield REST API. It supports tools for creating invoices, managing stores, tracking payments, and performing Lightning Network operations.

AI-powered smart contract forge with an 8-agent adversarial security audit system. Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains.

Provides Claude AI with direct access to Everclear.org's API endpoints for querying intents, invoices, analytics, and performing blockchain operations.

An MCP server that enables AI agents to interact with the STRATO blockchain platform and its DeFi ecosystem. It provides 67 tools for managing token balances, executing swaps, handling lending operations, and performing governance tasks.

An MCP server that provides access to Stern, a philosophical AI mentor combining rationalist thinking with stoic philosophy to guide users through personalized mentorship and smart contract accountability on Solana.

A server that adds Bitcoin payment capabilities to LLMs, enabling sending/receiving payments, creating charges, managing wallets, and performing other Bitcoin Lightning Network operations.

Enables AI agents to participate in a decentralized network, earn GSTD tokens by performing computational tasks, and communicate via the A2A protocol.

Enables AI clients to discover, trust-check, and pay for Algorand x402 services in USDC, with policy-guarded spending, relay fallback, and an audit ledger.

An MCP server that lets AI agents access higher.fun's open-source Solana launchpad through the public API and Solana RPC for scanning launches and trending coins, inspecting trades, holders, candles and safety data, checking creators and performing rug checks. It is currently read-only and requires no API keys.

Enables browsing an AI agent marketplace, viewing profiles and listings, and performing network actions such as matching, escrow, and subscriptions through the Zetto network.

Enables AI agents to pay x402 endpoints on Cardano through a policy-gated wallet with spend caps, payee allowlists, human approval, and an audit log.

Enables MCP clients to enforce deterministic budget gates and persistent audit trails for model-driven tool purchases, with stdio tools bound to an existing task.

Provides AI agents with tools to purchase a starter audit or triage for legal USDC earning routes, supporting checkout, triage, and payment processes.

Enables users to verify whether an ERC-8004-registered agent is currently reachable by resolving its on-chain registration and performing a live MCP handshake, returning verdicts such as REGISTERED_UNREACHABLE or AGENT_NOT_FOUND.

Provides MCP tools to enforce spend policies (allow, deny, step-up, allowlist) on agent wallets with an immutable audit trail.

Checks live x402 routes across Base, Solana, and Algorand before agents spend. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Optional signed route-binding receipts support buyer-side checks.

Provides read-only tools to query live Polymarket prediction-market data via the public Gamma API, enabling search, browsing, and detailed market and event information.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Enables agents to search and inspect live service offerings, generate x402 payment snippets, and understand blockchain-only balance policies.
